Abstract

Die Erfindung betrifft ein Verfahren zur Durchführung der Zuordnung der Radposition zu Reifendruckkontrollvorrichtungen 6a - 6d in einem Reifendruckkontrollsystem eines Kraftfahrzeuges. Die Reifendruckkontrollvorrichtungen 6a - 6d senden in vorgegebenen zeitlichen Abständen ihre individuelle Kennung an die Zentraleinheit 10 des Reifendruckkontrollsystems. Zu den Sendezeitpunkten nimmt das Rad, von welchem aus die individuelle Kennung übermittelt wird, eine definierte Winkelposition ein, so dass zwischen zwei Sendezeitpunkten ein definierter Winkelversatz vorliegt. Die von den Drehzahlsensoren 4a - 4d gelieferten Umdrehungssignale werden in der Zentraleinheit 10 dahingehend überprüft, welches Umdrehungssignal den gleichen Winkelversatz aufweist. In der Zentraleinheit 10 wird die Reifendruckkontrollvorrichtung 6a - 6d derjenigen Radposition zugeordnet, dessen Drehzahlsensor 4a - 4d ebenfalls den vorgegebenen Winkelversatz gemessen hat.

The invention relates to a method for carrying out the assignment of the wheel position to tire pressure control devices 6a-6d in a tire pressure control system of a motor vehicle. The tire pressure control devices 6a-6d send their individual identification to the central unit 10 of the tire pressure control system at predetermined time intervals. At the time of transmission, the wheel from which the individual identifier is transmitted assumes a defined angular position, so that there is a defined angular offset between two transmission times. The rotation signals supplied by the speed sensors 4a-4d are checked in the central unit 10 to determine which rotation signal has the same angular offset. In the central unit 10, the tire pressure control device 6a-6d is assigned to that wheel position whose speed sensor 4a-4d has also measured the predetermined angular offset.
